Detailed Description
Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In this description, specific shapes, materials, numerical values, directions, and the like are examples for facilitating understanding of the present disclosure, and may be appropriately changed in accordance with the application, purpose, specification, and the like. In addition, it is assumed that the following is appropriate to combine the features of a plurality of embodiments and/or modifications, and the like, and use them.
Fig. 1 is a perspective view of a rotary electric machine stator 10 according to an embodiment of the present disclosure, and fig. 2 is a view partially showing a cross section taken along line a-a in fig. 1. The rotating electric machine stator 10 is simply referred to as "stator 10" hereinafter.
As shown in fig. 1, the stator 10 includes: a stator core 12; a coil 30 wound around the stator core 12; a power wire 50 connected to the coil 30; and a resin mold 60 provided to cover the coil end of the coil 30. A cylindrical space is formed inside the stator 10, and a rotor, not shown, is rotatably provided in the space, thereby constituting a rotating electric machine.
The stator core 12 is a substantially cylindrical magnetic member. The stator core 12 is formed by laminating magnetic thin plates such as electromagnetic steel plates in the axial direction and integrally connecting the laminated magnetic thin plates. The stator core 12 includes an annular yoke 14 extending in the circumferential direction and a plurality of teeth 16 protruding radially inward from the inner circumferential surface of the yoke 14. The plurality of teeth 16 are arranged at intervals (equal intervals) in the circumferential direction. A groove 18 is formed between two circumferentially adjacent teeth 16. The groove 18 is formed in a groove shape that opens radially inward and opens on both axial sides.
Further, a mounting portion 20 is formed on the outer peripheral surface of the stator core 12. The mounting portion 20 is formed to extend in the axial direction of the stator 10 and project outward in the radial direction. In the present embodiment, three mounting portions 20 are arranged at equal intervals in the circumferential direction (only two are shown in fig. 1). The mounting portion 20 is formed with a through hole 22 extending in the axial direction. The stator 10 is fixed to a housing (not shown) by bolts (not shown) inserted through the through holes 22.
The coil 30 is wound around the teeth 16 mounted to the stator core 12. The coil 30 has coil ends 31a, 31b protruding from the axial end faces of the stator core 12. In the present embodiment, the coil 30 is formed of a coil segment wound around the stator core 12 in a distributed winding manner. The coil may be wound around the teeth of the stator core in a concentrated winding manner.
The coil segment is formed using a plurality of wire segments 34 formed of flat wires in a substantially U shape. The wire segments 34 are covered with an insulating film except for the head ends of the two straight line portions. The coil segment is configured as follows, for example. The two straight portions of the wire segment 34 are inserted from the axial side into the two slots 18 circumferentially separated by the predetermined number of slots 18. Then, the head end portion of the straight line portion protruding from the slot 18 on the other axial side is bent to approach the other wire segment. Then, the tip end portions of the straight line portions of the other wire segments adjacent to each other in the radial direction are joined by welding or the like. Thus, a coil segment wound over a plurality of teeth 16 separated by a predetermined number of slots 18 is formed.
One end portions of the coils 32U, 32V, and 32W of the respective phases are electrically connected to each other at a neutral point not shown. On the other hand, the other end portions (input-side end portions) of the coils 32U, 32V, and 32W of the respective phases are drawn radially outward and connected to one end portions of the power lines 50U, 50V, and 50W of the respective phases.
The other ends of the power lines 50U, 50V, 50W of the respective phases are connected to terminals 52U, 52V, 52W. These terminals 52U, 52V, and 52W are connected to an external circuit such as an inverter, not shown. Thereby, a three-phase ac voltage is applied from an external circuit to the coil 30.
As shown in fig. 2, the lead wire 36U, which is the input-side end portion of the U-phase coil 32U, has a radial portion 38a extending radially outward from the inner peripheral side of the stator core 12 and an axial portion 38b bent in the axial direction. The tip end of the axial portion 38b of the lead wire 36U is connected to one end of the U-phase power line 50U via the joint 40. The joint 40 is formed by welding or the like, for example. The U-phase power wire 50U extends from the joint portion 40 along the axial portion 38b of the lead wire 36U, and extends to the other end portion to which the terminal 52U is connected, bent by about 90 ° as shown in fig. 1.
The lead wires of the V-phase coil 32V and the W-phase coil 32W are connected to the respective one ends of the V-phase power line 50V and the W-phase power line 50W via the joint 40, as in the case of the U-phase coil 32U described above. As shown in fig. 1 and 2, the lead wires 36 of the coils 32U, 32V, and 32W of each phase and the joint portions 40 of the power lines 50U, 50V, and 50W of each phase are located at positions separated radially outward from the coil end 31b and are arranged at intervals in the circumferential direction. The joint portion 40 is located radially outward of the outer peripheral surface of the stator core 12.
The stator 10 of the present embodiment includes a resin mold 60. The resin mold 60 integrally fixes the coil end 31b of the coil 30 and the joint 40 between the coils 32U, 32V, and 32W of the respective phases and the power wire 50. The resin mold 60 is suitably made of an insulating resin such as varnish. However, the resin mold 60 is not limited thereto, and may be made of a thermosetting resin such as an epoxy resin.
The resin mold 60 has a coil end fixing portion 62 that is annular and covers the coil end 31b, and a joint portion fixing portion 64 that is integrally formed to protrude radially outward from the coil end fixing portion 62 and covers the joint portion 40. The coil end fixing portion 62 has a function of improving electrical insulation between the coils 32U, 32V, and 32W of the respective phases by covering the welded portions of the head ends of the lead segments 34 constituting the coil 30 with an insulating resin. In the present embodiment, the three joint fixing portions 64 are separated from the joints 40 of the power wire 50 by the coils 32U, 32V, and 32W of each phase, and protrude in a substantially U shape in an axial view. By integrally fixing the coil end 31b and the coils 32U, 32V, and 32W of each phase to the joint 40 of the power wire 50 by the resin mold 60 in this manner, the power wire 50 can be stably fixed via the joint 40 with a simple structure without requiring additional components such as a power wire fastening member and a support bracket. As a result, when the rotating electric machine including the stator 10 is mounted on a vehicle or the like and operated, the breakage of the joint portion 40 due to the resonance of the power line 50 can be effectively suppressed. The three joint fixing portions 64 are formed to protrude so as to be separated from the joints 40 of the power wire 50 for the coils 32U, 32V, and 32W of the respective phases, and thus the amount of resin material used for the resin mold 60 can be effectively reduced.
In the resin mold 60, a surface 66 opposed to the stator core 12 is formed as a flat surface. This is because, when the resin mold 60 is molded as described later, the surface 66 is defined and formed by the liquid level of the liquid resin material stored in the mold groove.
Next, a method of manufacturing the stator 10 will be described with reference to fig. 3 and 4. Fig. 3 is a flowchart illustrating a method of manufacturing the stator 10, and fig. 4 is a diagram illustrating a state in which the resin mold 60 is molded.
As shown in fig. 3, first, the stator core 12 is prepared (step S10). Next, the coil 30 is wound around the stator core 12 (step S12). Next, the power wires 50U, 50V, and 50W are welded to the input-side ends of the coils 32U, 32V, and 32W of the respective phases of the coil 30, respectively (step S14). Then, the other axial side coil end portion 31b and the joint portion 40 are integrally covered, and the resin mold 60 is molded (step S16).
As shown in fig. 4A, in the mold 70, the liquid resin material R is stored in a mold groove 72 formed in an annular shape. In this state, the coil end 31B of the stator core 12 around which the coil 30 is wound and the joint 40 are directed downward, and as shown in fig. 4B, the coil end 31B and the joint 40 are immersed (immersed) in the resin material in the mold groove 72 from above. Then, the mold 70 is removed after the resin material R is cured.
The resin mold 60 is molded by immersing the coil end 31b and the joint 40 in the resin material R in this manner. Therefore, a complicated mold structure is not required, in which the resin material R does not leak out between the lead segments 34 constituting the coil 30 and the mold 70, and the mold cost can be suppressed.
The rotating electric machine stator of the present disclosure is not limited to the above-described embodiment and the modifications thereof, and various changes and improvements can be made.
In the above, the example in which the joint fixing portion 64 of the resin mold 60 is projected so as to be separated for each joint 40 of each phase coil 32U, 32V, 32W has been described, but the present invention is not limited thereto. For example, as shown in fig. 5, the joint fixing portions 64 of the resin mold 60 may be formed so as to be connected in the circumferential direction so as to fix the three joint portions 40 of the coils 32U, 32V, and 32W of each phase collectively. This increases the strength of the joint fixing portion 64, and the power wire 50 can be fixed more stably.
